The result from tests for the main concrete or reinforcement deterioration processes, including chloride diffusion, carbonation depth, sulfate resistance, freeze/thaw and abrasion are given in Table 2. Again, expected behavior in terms of the effects of design strength on each property was obtained, but no influence of pfa fineness was found. Tests on variable LOI pfa concrete indicated that LOI also had little or no effect on durability up to a /Loi of 8.0%
